My usual dive buddy (husband) can't make the next trip with me. My non-diver sister said she'd like to come. She knows I will be diving and probably not back until at least 1:30. She's not someone who will want to spend all day at a beach or hours on end shopping. Since all my Coz trips have been dive trips I hate to admit, but I haven't really done a whole lot on the island. I'd love to have her come with me, but I'm not sure there will be enough for her to do. If you travel with a non-diver, what activities do they do while you're diving?
